Serious Help needed.

Someone changed my hotmail password because I think I left it open at school. Is there a way to get it back?
My email Adress was : irm1902@hotmail.com
I tried to recover password by it didn't work because I can not remember what did I put in for my location 4 years ago when I created the account. And I did not put in an alternative email.

sniff the network to find out if anyone is logging in to the account, and if someone does you will see the password in clear text using cain and abel from http://www.oxid.it try that, but other than that I am not sure what else to do.
